The Dutch version is baljuw, but it is a term which has had many variant
spellings over the ages: Bailluw, Baliow, Ballif. The linkage to the
English term Bailiff can be clearly seen in these variants.

A charter granted to the people of Holland on 26.05.1480 by Duke Maximilian
notes in article 9 that [Van Leeuwen] "..no baljuw, schout, nor dikereeve,
within the towns or villages, shall administer justice except in a public
court... " (Source: see 1 below, Van Leeuwen p 353) The baljuw used also
to enjoy 1/3 of all forfeitures occurring in their districts in all corporal
and criminal cases; and for the other two-thirds they were obliged to
account to the Count. (Van Leeuwen, p354)

There was also a "Court of Baljuw and well-born men" - the Hooge Vierskaar.

The South African Legal Dictionary, quoting Van Leeuwen, makes reference to
a Baljuw (or Aesge) in early Frisian law too. (SALD, p 2)

Jan Matthyse's Rechtboek v.d. Briel, written in abt 1400, also makes
reference to the office of Baljuw.

With respect to the word's "ancestry":
Baljuw is most probably derived from the Old French Bailie, which in turn is
derived from medieval Latin bajulus. Bajulus was i.a. the term for someone
who bears burdens, also a letter-bearer (SALD, 60-61)
